Application filed July 1912. Serial-N 0-. 711,571.

To all whom it may concern Be it known-that I, WVILLIAMkH; Hoornn, a citizen of the United'States, residing at Salem, in the'county of EsseX and Stateof Massachusetts, have 1 invented: an 1 Improvementin i Machines: for Treating. Boots and Shoes, of .which the-following:description, in connection with the accompanying drawings, isia specificatiom like lettersflonithe drawings representing like parts.

The invention to be hereinafter described relates to machines ion-treating boots: and shoes,''- and moreparticularly -to su ch. ma chines where the booton shoe is mounted-or sustainedupon a support! during the uaction of atool thereon.

Inmachines of this general type it-isidesirableupon the completion oftheproposed operation on a boot or shoe that the machine be automaticallybrought to rest. i Difliculty has been experiencedin some cases, however,

ineffecting an interruptionof theoperative relation of parts on the train of mechanism at the instant-when the machine is-to be stopped,- With the result that the machine has not always-acted as intended or. some portionshave been broken, or subjectedto excessivewear and strain.

With these and other fa'cts in view; T- the present inventionai1ns-to--provide means, whereby preliminarily to r or .at i the time of the operation of the. stopping "means; T the strain of driving-engagement :of some portion of thetrain ofinechanismwill berelieved, thereby facilitatingv the actioneofg the stopping means, all= of whichwill chest-be made clear from the following description and accompanying drawings of. onev form of means for carrying the invention-into :practical effect; it "being understoodrtha-t theinvention is: not restricted to l-the" particular means shown butmay be variouslymodified laying or leveling machine, and-nmreespecially to such type'ofmachine as shown. and described in application Serial No. l5l,082, filed September 21, '1908,but it is to be un-. derstood that it is not necessarily restricted thereto and may be employed inzotheramachines either of that c or rdifierent type, wherein vthe boot,v or shoe is sustained by. a worksupport :du ring the action ,of a .to'ol.

V

The present. form and embodiment of the invention contemplates the provision of twin ma'chinesnon {the conexframe, :that is: there may. be two similar. operativedevices. which, for. convenience; and. economy, may be zalternatelv operated, so that While ,the,-.oper'ator is-adjusting a bootor shoe .to.- the Work sup porteof onemachine, the othenmay betreat ingca shoe previously suppli'ed,.and asfl said twin machinesare ormay be alike, adescriptionioflone will be sulficient, itbeing understood also that one machine alone may be employed, if desired. 1

Loosely mounted on the clutch shaft 9 are the two similar gears 12, 12, each of said gears being held from longitudinal movement by suitable means, such for instance, as a sleeve or bushing 13 secured to the shaft by a pin 14 and engaging a collar 15 between itself and a bearing 16, said collar being loose on the shaft and connected to the gear 12 by suitable means, such as the screws 17. Obviously other expedients may be employed for loosely mounting the gears 12 upon the clutch shaft.

Each of the gears 12, Fig. 4, has a hub 18,

the face of which constitutes one member of a clutch, the other member being formed by a part 19 splined to the clutch shaft, and having a circular recess 20 engaged by a roller 21 carried by an arm of a bell crank lever '22, pivoted at 23 to a bracket or part 24 of the machine frame. A spring 25 disposed between the clutch members 19, normally tends to move them into engagement with their cooperating clutch members 18, when said clutch members 19 are free to move. 1

Each of the bell cranks 22 has a tail piece 26 to which a spring 27 is connected, said spring tending to hold the arm 28 of the bell cranks against the periphery of a clutch controller 29 provided with raised and depressed portions 30 and 31 respectively, Fig. 2. Obviously when the end 28 of a bell crank lever rests upon a raised portion 30 of the controller, the connected clutch member 19 will be held out of engagement with its cooperating member 18, and when the end 28 moves into a depressed portion 31 of the controller, the spring 25 will be per mitted to move the clutch members into engagement. If at this time the high parts of the clutch faces are opposed to each other, however, the member 19 cannot move longitudinally of the clutch shaft until the latter has been rotated to carry the high parts of the clutch members from opposed relation. The bell crank 22, however, is under the influence of the spring 27 which maintains the end 28 on the clutch controller, and such turning movement is permitted under the conditions noted byv making the circular recess 20 of increased width, as shown.

The clutch controller 29 is mounted upon a stud 32, Figs. 2 and 4, secured to a bracket or arm 33 connected to the machine frame,

an arm 41 rising from the treadle 42, Fig. 1. A spring 43 normally holds the treadle raised and the said rod 39 pushed rearwardly, the pawl 35 at such time being in engagement with one of the teeth of the ratchet 34 and in position to turn the same the desired distance when the treadle is depressed.

Pivotally mounted at 44-, Fig. 4, on the bracket or arm 33 is a yielding locking arm 45 carrying a roller 46 adapted to engage depressions in the clutch controller and yieldinglv lock the same from rotation in either direction, but yet permit the ratchet to turn the controller when actuated by the treadle, as already described. To cause this yielding lock action, the arm 45 is engaged by a spring 47, the opposite end of said spring being secured to a fixed part of the machine frame and normally acting to hold the roller 46 against the periphery of the controller, the ends of said spring being clearly indicated in Fig. 4, all as fully disclosed in Patent No. 1,041,668.

From the construction thus far described, it will be apparent that upon depression of the treadle, the pawl 35 will rotate the ratchet 34 and turn the clutch controller a suitable distance to cause its raised and depressed periphery to act upon the arm 28 of the bell crank so that, assuming the arm 28 to be resting on a raised portion of the clutch controller in which position the clutch members are disengaged and the treadle to be depressed, then the clutch controller will be moved to permit the end of the arm 28 to drop into a depressed portion of the controller, whereupon the clutch members become engaged and the connected gear 12 rotated. The above is a good and practical form of starting device, but it is to be understood that the invention is not restricted thereto and that various expedients may be employed under the control of a treadle or other manually operated device to engage parts of the train of mechanism which give to the machine its operative action.

Mounted on a shaft 48,. Fig. 1, is a camfaced gear 49, meshing with the smaller gear 12 on the clutch shaft so that when the gear 12 is rotated, as hereinbefore explained, it imparts rotation to the cam gear 49 from which some of the characteristic motions of the parts of the machine are derived, as

for instance, is clearly set forth in the application to which reference has been made. It is sufficient at this time to state that when the cam gear 49 has made one complete rotation from a point somewhat in advance of that indicated in Fig. 1, one full cycle of the machine operation has been made, and it is then desirable to bring the parts to rest automatically. To secure this automatic stopping of the machine, the cam gear 49 has pivotally mounted thereon at 50, Fig. 1, a

trip finger 51having' a tail piece 52 normally held against a stop-pin on the face of the gear by a spring 53, the free end of the trip finger at such times projecting so as to engage a recess 54:, Fig. 2, in the periphery of the clutch controller. From this it will be clear that as the cam gear completes its rotation under the actuation of the gear 12, the end of the stop finger will engage: a re cess in and turn the clutch controller to cause a high part thereof to pass beneath the end of the arm 28 of the bell crank and, perforce, move the connected clutch member out of engagement with its coacting member, thus stopping the machine, substantially as pointed out in the application to which reference has been made.

In the character of machine illustrated, there is mounted near the top thereof a former and its actuatingv devices,videntified as a whole in Fig. 1 by A, said former being provided with a patterned surface generally complemental to the surface of the shoe sole to be treated, although-this character of former is not essential; and opposite thereto is the coacting shoe support,

generally designated by B, said former and shoe support being adapted for certain relative movements to'effect the proper laying and leveling of a shoe sole, all as clearly pointed out in the application mentioned.

Guided for rising and lowering-movement 1n the machine frame is the shoe support,

Fig. 1, whichvmay comprise a table 55 having appropriate side bearings sliding on and guided by the tie rods 5.

Mounted upon the table 55 is the ack 56 which may be of any appropriate character for supporting or sustainmg a shoe during the action of the tool or former thereon, and said jack,'as pointed out in said application, may have appropriate movement imparted thereto lengthwise of the table.

The shoe support comprising in the present form of the invention, the table 55 and its jack 56, is appropriately connected to the arm 57 of a lever pivoted at 58 at the lower part of the machine frame, the other arm 59 of said lever being provided with a roll 60 traveling on the periphery of a cam 61 carried-by the cam gear 19,as clearly indicated by Fig. 1 of the drawings, and as fully pointed out in the application heretofore mentioned. The shoe support may be connected to the arm 57 of said lever in any approved manner, as by the rod 62*, shown by dotted lines in Fig. 1, jointed to the arm 57 of said lever substantially as pointed out in the application mentioned, and since these features of construction form no essential part of the present invention, and are well understood by those skilled in the art, it will be sufficient to note that the shoe support comprising the parts noted, is sustained by the arm 57 of the said lever and that it embodiment of the present invention, it will be noted that upon depression of the treadle 12, the operation of the machlne is started, the gear 12 on the cam shaft turning the cam gear 49 and raising the shoe support,

through the connections described, to bring the latter into operative relation. with the tool or form. When the machine has made its cycle of operations the finger 51 meetsand aotuates theclutch controller to cause the machine to come to rest. At this time, however, if the driving strain between the engaging portions of the clutch members is maintained, difficulty will be experienced in disengaging the clutch members, and the present invention contemplates the provision of means for relieving the driving stress between the clutch members preliminarily to, or at the time when the machine is to be stopped, so that the clutch members may be readily disengaged, and in the form of the invention herein illustrated, advantage is taken of the weight of the shoe support to case the stress between the engaging parts of the clutch members, as will now be described.

By reference to Fig. 1 it will be noted that the cam gear 49 rotates clockwise during the cycle of machine operation and that the high portion of the cam 61 presents a dwell for holding the shoe support in raised position for the action of the laying and leveling form upon the sole of a shoe mounted on said support, and that upon the completion of the laying or leveling action the low part 62 of the cam 61, acting through the lever described, permits the shoe supports to move downward, the weight of the shoe support, however, being still sustained from said cam through said lever. WVhen the shoe support has been thus lowered and the jack moved outward or to the front of the machine for removal of the treated shoe, it is desirable that the stopping devices act to stop themachine, and to relieve the driving strain between the clutch members at this time, the cam 61 is provided with a part 68, so inclinedwith respect to the low portion of the cam that the weight of the shoe support acting through the arm 59 of its supporting lever imparts tothe cam gear 49 a forward impulse in the direction of its rotation thereby relieving the driving strain between the engaging portions of the clutch members so that their disengagement may be readily effected and the machine brought to rest.

It will be noted by viewing Fig. 1 and Fig. 3 that the roll 60 on the shoe supporting lever arm 59 acts upon the incline 63 just prior to or substantially at the time that the finger 51 acts to turn the controller to effect machine stoppage, so that at the moment the clutch members are to be separated the cam gear 49 is given a forward impulse under the weight of the shoe support and the driving strain between the members of the clutch is relieved thus facilitating the action of the stopping means.

While the invention has been exploited herein in connection with a laying or leveling machine it is obvious that it is not limited to such machine, but is applicable in any shoe treating machine where theshoe support is sustained during the action of the tool and its weight is applicable for imparting a relieving impulse to the train of driving mechanism that their operating relation may be interrupted.

What is claimed is 1. In a machine for treating boots and shoes, the combination of a shoe support, a

tool for acting on a shoe sustained by said support, stopping means for the machine ineluding clutch members, and means for causing the Weight of theshoe support to ease the operative engagement of the clutch members when they are to be disengaged. V
